TRANSLATING DEVICE.

Application filed October 31', 1921. Serial No. 511,785.

T 0 all whom it may concern:

Be it known that I. MERLE PEABODY CHAP- LIN, a citizen of the United States, residing at White Plains, in the county of VVestchester, State'of- New Yorlcfhave invented certain new and useful Improvements in Translating Devices, of which the following is a \full,.clear, concise, and exact description.

This invention relates to apparatus for translating current impulses into mechanical movements. It is particularly applicable for use in printing telegraph systems, although it may be used for the remote control of power switches, linotype machines and the like.

All object of the invention is to. provide positive means for distributing and storing code combinations of signaling impulses and translating the impulses into mechanical movements.

Another object is to provide distributing,

storing, and translating means, requiring a minimum number of electrical parts.

The application in general comprlses a plurality of members, each of which is adapted to occupy either of two positions, depending unon the character of the respective signals. The members, when-operated, may control local circuits or actuate work members, as desired.

Referring to tnc drawings:

The invention in general comprises an operating unit B, which has power communicated thereto'from a continuously rotatingmotor 5 through. an electromagnetic releasing unit A Both of the units Aand are rigidly secured to a sleeve 10 connecting discs or cams 19 and 23. The stop arm 12' and the cams 19 and 23 are normally held against rotation by means of a latch 15 under the control of release magnet 16 for periodically allowing the stop arm and the associated cams to be revolved by means of discs of friction material 11 and 18, the disc 11 being held by a metal disc 4 while the disc 18 is positioned by a gear wheel 17. A nut on the. end of the shaft/7 compresses a spring 21 against gear wheel17 which is secured to the shaft 7 b means of a sliding key. Pressure on the gear 17 grips cams l9 and 23, the latter of which is on the left of stop arm 12 and is in engagement with the chanical lock and a mechanically operated means for restoring the same to its locked positionjust prior to completion of the cycle of rotation by the stop arm 12. For locking the latch 15 in position 'a l1 orizontally extending member 38 having a notch formed in the free end thereof, and which is held in operative relation with the portion 40 of the bell crank lever by a coiled spring 71. is pivoted to the frame holding the release magnet 16. Thus when the armature 37 of the release magnet 16 is attracted. the member 38 will be lifted out of engagementw-ith portion 40 and thereby unlock the latch 15.

Further travel of armature 37 rotates the bell crank lever and positively the latch 15 out of the path of the stop arm 12 which will then be free to rotate. Just prior to the completion of the cycle of rotation by the stop arm 12, the pivoted member 41 is o 'erated bv the stop arm, whereby the bel crank lever is rotated so that. the notch on the member 38 engages the portion of this bell crank lever and positions the latch 15 in the path of the stop arm 12'for arresting the rotation thereof. I

Disposed to the left, of the ston arm 12 is the circular disc or cam 23 having a link 24 normally in engagement therewith, which serves to effect the rotation of its associated rod 25 through a'small angle. This linkis rigidly secured to the operating rod 25 which serves to move a stop arm 26 upon the movement of link 24 by the cam 23 into the path a part of the operating unit B, a transfer switch 32, as shown in Figs. 3 and 4, is provided. The transfer switch comprises a pair of oppositely disposed contact arms 33 and 34, which are insulated from one another by means of insulation. material 35 and are secured "in place by an L-shaped member 36 secured to the base 6. Arranged to be moved between thecontacts 33 and 34 is a spring operated member 39 carrying contact points for engaging those secured to the members 33 and 34. For operating the member 39 following the energization of the release controlmagnet 16, an operating link 42 rigidly secured to a shaft 43 is provided, and which is in operative to the ir-- regular-shaped disc 19. Therefore, upon rotation of the disc 19 and the shaft 7 with whichit is revoluble through the friction discs 11 and 18,.the operating'link 42 is moved a distance sufiicient to cause rotation of the operating rod 43 through a small angle, and consequently actuation of the contact making member 39 of the transfer switch 32. In this manner the line circuit will be transferred from the windings of the release control magnet 16 to the operating magnets 29 and 30, which will be energized,

depending upon the character of the incommg signaling current impulses. Immedi ately following thereception of the last impulse by either of the operating magnets 29 and 30,1an operating link 44, operating in conjunction with thefcam 23, transfers the line circuit from the operating magnets 29 and 30 back totherelea'se control magnet 16.

' The operating unit Bi comprises a shaft 46 extending between a pair of uprights 47 and 48, and'o eratively connected witlnthe shaft 7 throug a friction clutch, which 'consists of a pair ofcirculardi-scs .49 and'50, rigidly secured to the shaft 7. Equally and 83, or effect mechanical positions cgeanae spaced about the circumference of the discs on each-side of the metal disc'52 are metal plates 53 and 54 which are rigidly secured to the shaft-46 and have on each side thereof discs of friction material continuously rotating with the shaft 7. In order to secure good contact pressure between the plates 49 and 50, and the discs of friction material, a plurality of coiled springs 55 are provided.

Spaced equal distances along the shaft 46 and at different angles from a longitudinal plane are a plurality of operating vanes 56, 57, 58, 59 and 60, which haveon thefree end thereof knife-like projections 70.. The vanes 56 to 60 inclusive serve to effect-movement of bifurcated members individual thereto, which causes the opening and closure of, the electrical circuits extending to the selecting magnets of a receiving printer or effects mechanical positions or selections.

Rig'idly secured to the uprights 47 and 48 is an irregular-shaped member 61 to which the bifurcated members .63, 64, 65,

66 and 67 ,having an irregular shapedcol lar 69 on one side. thereof, are mounted. Also secured to the mem or 61 is a member 68, corresponding to each of the bifurcated members, which has oppositelyivotally entending projections 73 and 74 serving to direct the movement-of the vanes secured to j tegral with a member 76 secured 'to'the '1 I member 61. In order to. deflect-the operate in 'vanes to one side or the other of the b1 urcated members 63 to 67,- inclusive, in

accordance with the desired codecombination. of message impulses, a member 78slidable longitudinally, and having wedgeshaped projections 79 correspondi'ngto the IJI'QJBCtlOIlS 75, is arranged under the control of the operating magnets 29 and 30.

As shown in Fig. 1, the member 78 is ar- T ranged to be moved in one-direction upon the energization of magnet 29 through the medium of the armature 80, and in the op F posite direction due to the .energization of theo'perating magnet 3O.v Thus. upon the energization of'these, magnets, which mage nets will be energized in accordance with the signaling current. impulses, the ibifurcated, members 63 to 67 i l i will be, Opp erated to eflect'the closure of circuits tending through their associated contacts 82 lections.

Immediately after member 63 hasbeen actuated by its'operatthe last bifurcated ing vane 56,, a. cam84 onthe shaft 46,";is brought into operative relation with a link I 86, which is secured to ashaft '88. -This menses shaft 88, serves upon being rotated, to cause the rotation of shaft 89, and consequently the release of shaft 96,, forming a part of the printer mechanism.

A receiving printer of the character with which a distributor mechanism ofthe type herein described is especially applicable is disclosed in my copending application,

Serial No. 424,372, filed November 16, 1920, and since. the above mentioned copending application illustrates and describes in de-- is linked with shaft 89, which in turn has secured at one extremity thereof one part of a toggle joint comprising members 90 and 91, as shown in Fig. 8, is rotated through a predetermined angle. By means of a spring 92, which has one end attached to the member 90, and the other to a support 98, the member 90 is thus normally retained 1n engagement with an adjustable stop screw 93. Ri gidly secured to the member 91 of the toggle joint is a block'94, arranged to be revolved about a shaft 97. mounted in the frame 100. "Due to the rotation of the shaft 89 and a similar motion of the mem- 90 and 91, a downward movement of the block 94 is effected. The block 94 thereupon moves to a position whereby a stop arm 95, carried by an operating shaft of the receiv ing printer, is released. The release of the stop arm 95'permits the shaft 96 to he revolved by power communicated thereto through a friction clutch forming a part of the printer mechanism.

Also rigidly secured to the shaft 46is a cam 85 arranged to operate a link 87, which is also secured .to the shaft 88. The position of thecam 85 on this shaft is such that following the rotation: of the shaft due to the operation of'the link 86, the link 87 is moved in a direction whereby the shaft 88 is rotated in a direction opposite to-thatmaused by the actuation of the link86 by the cam 84. In this manner the members 90 and 91 of the toggle joint will be restored to their normal position under the action of the spring 92, thereby placing the block 94 in the path of the stop arm 95, which will be arrested upon the completion of its cycle of rotation.v

ltn order to provide the proper time 1nterval between thereceipt of the releasing impulse and the release of the distributing unit B, the release magnet 16 together with the stop arm 12 is arranged to rotate about a bearing secured to the shaft 7. Thus the time interval between the release of the stop arm 12 upon the energization of the release control magnet 16 and the release of the stop: arm 27 secured to the shaft 46 may be varied so that the proper relation will exist between the initial impulse and the following or selecting impulses.

Fig. 10 illustrates a line circuit to which there is connected a transmitting distributor of the rotary or brush type, and a receiving distributor of'the type herein described.

The structure illustrated in this figure comprises in general a transmitting dis-' tributor 103 consisting of an inner and outer ring over which a brush arm 104 is designed to pass. The outerring is divided into a plurality of segments which are connected to the contacts of a tape transmitter or any well-known type of transmitter. The brush arm 104 is normally held against rotation by means of a latch 105 which. is under the control of a release magnet 106. Upon energization of the release magnet 106, the brush arm 104 is free to make one revolution, power being communicated thereto through a slip friction clutch in a manner well-- known.

A' distributor of the character--'hereinbefore described, has its operating magnets 29 and 30 connected with the contact-s of a receiving relay 107, which has its windings connected in the ratio arms, formiing a part of theline conductor 108 extending to the distant station. As .in all signaling systems of the type wherein the real line is balanced against an artificial line, the receiving relay is constructed so as to be nonresponsive to outgoing impulses, but responsive to incoming impulses. To the contacts on the distributor illustrated. in the rectangle 109, there. is connected the windings of the operating magnets 110, 111, 112,

113, and 114 of the receiving printer.

The operation of'the system is as follows: Assume for the sake of clarifying the description that contacts 115, 117 and 119 of the transmitter are closed to connect the corresponding segments of the distributor 108 to a source of battery, and, that the distributor arm 104is released for rotation. Immediately following the release of the distributor arm 104 and the passage over segment 120, an open circuit condition is established whereby the receiving relay 107 at the distant station is caused to reverse the position of its armature- The reversal of the armature of this relay completes an energizing circuit for the release control magnet 16zat that staution. Upon the ener gization' of this magnet, the stop arm 12 carriedby the sleeve 10 is free to rotate to ground.

through the friction discs 11. and 18, and I closed. battery is applied to the. line 103 upon the passage of the brush arm 104 over the corresponding segment of the distributor whereupon the receiving relay 107 again reverses the position of its armature and establishes an energizing circuit extending from battery, armature of relay 107, contact 121, winding of operating magnet 30, contact 33 and switch member 39,;

As previously described, the shaft 46 is released for rotation after the shaft 7 has beenrotated through a pre-- determined angle. Thus the vane individual to the bifuracted member 67 will be shifted upon its continuous rotation to the left-hand side of this member, but since this member had previously been positioned to make contact with its right-hand contact no movement thereof is brought about by .the movement of the vane in this manner;

Upon the passage of the brush arm over. the segment to which the contact 116 is connected, an open circuit condition is established to the line conductor 108 whereby the receiving relay 107 is actuated to open-(1on tact 121 and close contact 122 The closure of contact 122 establishes an energizing cir- .cuit for. operating magnet 29 extending from battery, through the armature of relay 107, contact 122, winding of operating magnet 29, contact. 33 of the transfer switch 32, and switch member 39 to ground. The bar 78 carrying the wedge-shaped projections 79 is thereby moved to the left so thatupon the rotation'of the shaft 46 and the engage. ment of the operating vane individual to the bifurcated member 66, vane 59 will be deflected to the right of this member so that upon its continued rotation the member 66 is caused to move from its associated right-hand contact to its left-handcontact, thereby opening the circuit of selected magnet 113. As the brush arm 104 continues its rotation and passes over the respective segments of the distributor, the line'conditions depending upon whether the transmitter contacts are opened or closed will be altered to in turn efiect the'nnergization of receiv-- ing relay 107. In the combination chosen contacts 117 and 119 of the transmitter are closed,'thereby conditions similar to those described in connection with the transmission of the first selecting impulse will-"be established, but as in this case the bifurcated s members and 63 being already in contact with the right-hand contact, nomovement mouse thereof will be'efi'ected. Owing to the fact, however, that contact 118 of the transmitter is open for the particular selection chosen, the bifurcated member-64 will be moved in a manner similar. to that described in connection with the movement of the member 66 for causin a similar action to the selecting magnet individual thereto.

From the above description it is apparent that the invention provides a distributing mechanism wherein' the electrical impulses are translated into mechanical movements which later effect the closure of electrical circuits. Although the invention has been described in connection with a particular circuit arrangement, it is of course obvious that the mechanism may be applied to other types of equi ment without departing from t e spirit an sco e of the invention.
